Blake Griffin made news this summer when he decided to not play for Team USA at the 2014 FIBA World Cup because of a back injury. With rumors that he may have injured his back during the playoffs or perhaps by doing back flips while on vacation, Griffin recently cleared the air by telling the Los Angeles Timesthat the injury is not that serious:

“It’s less than a hairline and my back is not fractured. Everything is still intact,” Griffin said. “I can still come out here and I can do my workouts and I can do everything I used to do. I just shouldn’t be playing and practicing everyday this early.”

The injury hasn’t deterred Griffin’s off-season training this summer as his trainer Robbie Davis has been putting Griffin through a series of exercises to strengthen his back. From the Los Angeles Times:

“There’s no names to these exercises, so it’s hard for me to describe them. But it’s really just keeping his hip stabilizers really strong so that he can stabilize that area and the muscles that surround his lower back.” – Robbie Davis

Griffin hasn’t been working out alone with Davis as former NBA player, Sasha Vujacic, has been training with Griffin. Vujacic had a 10-day contract with the Clippers back in February and is hoping to make a team this season:

Sasha Vujacic has been working out this summer with Blake Griffin with an eye towards returning to the NBA this season.

Vujacic may seem like an unlikely training partner for Griffin but the two must have established a friendship during Vujacic’s brief stint with the Clippers. Check out the videos of their training sessions which includes cameos from Clippers big man DeAndre Jordan, Dallas Mavericks guard Devin Harris, and San Antonio Spurs reserve forward Austin Daye:

Griffin and Vujacic are definitely putting in work but the important thing is that they are having fun while doing it as Davis’s Instagram shows:
